Train Auto Horn

Compatible with Transport Fever 3 build 40425 (the October 22 stability update and its hotfix), tested in game.

Beta: feedback welcome! Tell me in the comments if a horn misbehaves.

Trains blow their horn, but only when you are close enough to hear it.

Whistle Board

• A classic "W" sign, found with the rail signals. Place it beside the track before level crossings, tunnels or anywhere you like.
• Trains travelling in the direction the sign faces blow their horn as they pass it. Trains going the other way stay quiet, so you can place one for each direction.

Horn on station departure (on by default)

• Trains blow their horn as they leave a station. Can be turned off in the mod settings.

Only when zoomed in

• Horns only play while the camera is zoomed in close, so a busy network seen from far away stays quiet. Choose Very close (150 m), Close (300 m) or Medium (600 m) in the mod settings.

Uses each train's own horn sound. Trains only. Achievements stay enabled.
